He says clouds will start spilling into the area Saturday afternoon.
"The good news is those clouds won't contain any rainfall," Schwenneker said. "They'll also act like a blanket in the atmosphere and keep some of the daytime heat with us."
Temperatures at the start of trick-or-treating will be in the 60s.
"As the sun goes down we'll drop into the 50s," Schwenneker said. "Still not bad and if your kids are like mine, they won't need a jacket, because they will be running from house to house."
There may be a few showers around by Sunday morning, mainly in the western part of the viewing area.
